A Method for Establishing e-Traceability to NIST High-Dose Measurement Standards

摘要

A method for establishing electronic traceability, or e-traceability, of customer measurements to NIST high-dose measurement standards through the use of a measurement conversion factor (MCF) for Bruker e-scan instruments has been developed. The intent is that this factor will be incorporated into an Internet-based transfer dosimetry system, while still maintaining a reasonable and acceptable uncertainty for such a service. The method developed will define a relationship between measurements made on e-scan instruments at customer radiation facilities and the reference e-scan measurements made at NIST, and incorporate any uncertainty for this method into an overall uncertainty calculation for providing an electronic absorbed-dose certification service.
